Migrating policies and credentials from one security store to another is called reassociation.

Both policy store and credential store data can be reassociated (migrated) from a file-based store to an LDAP-based store, or from an LDAP-based store to another LDAP-based store.

Because the credential store and the policy store must both be of the same type, when reassociating one store you must reassociate the other.
